Nickel

(nikl.) [Ger., a good-for-nothing fellow.] (Chem.) A metal which miners, being disappointed in not finding it to be copper, as they expected from the color of its ore, in contempt called kupfernickel (worthle copper). It is white, ductile, and malleable; it may be drawn into wire, or rolled into plates, but a very small quantity of arsenic destroys its ductility. It is attracted by the magnet, and, like iron, may be magnetized. Its sp. gr., when hammered, is 8-82. It is somewhat more fusible than iron; is not affected by air or moisture at ordinary temperatures, but is slowly oxidized at a red heat. It is found in meteoric iron, but is obtained chiefly from kupfernickel, its sulphur et, and the ores of cobalt, with which it is a ociated. Its equivalent is 29.6. It forms salts with sulphuric and hydrochloric acids. Symbol Ni. [s. 646] IMG:p0691_0.jpg:Gravür
